' Figures 5 and 5a are sections respectively on the lines :r1-m and y-y/ of Figure 3, showing the valve in its neutral position and Figures 6 and 6a are sections on the line and g/-g/ showing the valve in the discharge position.

Referring to these drawings, it will be seen that I have provided a lubricant containing tank which is designated l0 and which may have any desired shape or dimensions and that this tank is provided with the bottom 11 and below this bottom with a compressed air tank designated 12. This compressed air tank is provided with means whereby it may be connected to any suitable source of compressed air and the air `compressed therein to any desired amount and is also provided with the inlet valve-13 for this purpose as illustrated. This tank 10 with the air tank 12 is mounted upon a wheeled frame ofany suitable construction. I have illustrated the tank as being mounted upon two lat-eral wheels 14 and being supported by a forwardly projecting bracket 15 having therein a rotatable spindle forked at its lower end to receive the steering wheel 1G. This wheel is shifted by means of the handle 17 pivoted to the axle of the wheel 16 so that it may be swung down into a pulling or pushing position or swung up to the position shown in Figure 2.

The tank 10 is designed to contain lubricating oil which may be filled into the tank through the opening 18 and the top of this tank at its middle is raised to form' a housing 19.

receptacle comprising a base 20. a transpa rent cylinder 2l' of thick glass and a top 22. this top being held in place by the central screw 23 which extends down through the top and 'has screw-threaded engagement with the base 20, as shown in Figure 3. The top and base are provided'with the gaskets 24 and these are disposed in recesses in the top and base respectively. The screw 23 acts to hohl the top and base in oil-tight contact with the ends of the glass cylinder 21.

` Mounted within the hase is the upwardly extending pipe 25 which extends down through the base and which has a height de- V terniined bythe amount of'bit which the Mounted upon this housing is the filling vessel 21 is intended to hold. The base is formed with therelatively large port 26. Disposed below the base is the valve casing 27 wherein is disposed the rotatable or oscillatable conical valve 28 extending entirely through the valve casing and urged to its seat by means of the spring 29, which at one end he-ars against a washer l30 in turn bearing against the end of the valve casing and which at its other end bears against the adjusting nuts 31, The opposite end of the valve carries upon it the handle 32. This end of the valve extends through the housing l!) so that the valve itself is entirely protectedwithin the housing.

The valve on the line wof Figure 3 provided with a right angular passage 2 which is adapted, as shown in Figures l. and (i. to connect the port 2li either with an inlet pipe 34 leading from an auxiliary tank or with a discharge pipe Si?) leading out of the hood or cover 19 and connected to a hose 36, or which is adapted to he. shifted to a neutral position, as shown in Figure '5 where the pipes 34 and 35 will be entirely disconneeted from the port :2(3.

The valve on the line z/-y/ of Figure 2l as shown in Figures l. 5 andi" is provided with a right angular passage 23T and opposite the apex of this passage with a circumferentially extending groove or duet 23S-which extends through a quarter circle. When this valve is in the neutral position shown in Figure 5a, these passages 3T and 3S will be entirely out of operative position` but when the valve is shifted to one of its two positions, as shown in Figures 4: and (in. these passages will be shifted to connect the measuring vessel with the auxiliary tank or with a vent as will be now stated.

Disposed in the bottom of the tank 10 is an auxiliary tank 39 which is provided with an inlet valve 40 of such type that the lubricant contained within the tank l() will fiow by gravity into the tank ai) and fill this auxiliary tank. The pipe 34 extends downward through the top of the auxiliar)y tank and nearly to the bottom thereof and as before remarked, enters the valve casing as shown in Figures 4, 5 and (i. Extending downward from the valve casing is an air pipe 41 which opens into the top of the auxiliary tank. This pipe 41 enters the valve casing 27 directly opposite the pipe Entering the valve casing 2T at right angles to the pipe 41 is an air pipe 42 which at its upper end opens into the compressed air tank 12.

lVhen the valve 28 is shifted to its` neutral position as shown in Figures 5 and the pipe 34 and the discharge pipe 85 will be ent oll' troni coinnninieation with the interior of the measuring vessel while the duct Iii will he.

turned into such poistion that it will eon|' niunicate neither with the pipe 4l noi' the,

air pipe 42 nor with the pipe 25. Assuming that the measuring vessel is empty andit be desired to fill the measuring vessel with oil, the valve is turned to the position shown in Figures 4 and 4a.

Under these circumstances the pipe 34 is placed in communication with the port 26 so that the oil may flow from the auxiliary tank 3.) into the measuring vessel. At the same time the pipe 25 through the circumferential groove 38 on the valve is placed in communication with a vent 42 as shown in Figure 4i while the air pipe 4l is placed in communication with the air pipe 42 leading to the air tank. Under these circumstances air will pass upward through the pipe 42 and then downward to the pipe 41 to cause the oil within the auxiliary tank 39 to be forced upward through the pipe 34 and pass upward into the measuring vessel, while the air within the measuring vessel is allowed to pass off through pipe 25, the circumferential groove 38 and the vent 43. IVhen the vessel has been filled, the handle 32 ofv the valve may be shifted to a neutral position and the oil thus retained within the vessel or if it be desired to immediatel7 discharge the oil. the valve is turned to the position shown in Figures 6 and (W. Under these circumstances. the passage 33 is shifted so as to establish communication between the port 2U and the discharge pipe 35 and the valve connects the pipe 25 with the pipe 42 which leads into the air tank 12. Thus air passes from the air tank 12 upward through the pipe to the space above the oil within the measuring vessel and causes the positive discharge of this oil out through the port. 2G and out through the discharge pipe 35. At the same time air is being vented through pipe 41 and vent 43 from the auxiliarvtank so as to permit the auxiliary tank to be filled with oil.

As soon as the tank and the measuring vessel have been emptied, the valve 28 should be turned to its neutral position but in case by inadvertance the attendant does not do this, the only effect would be to cause the air from the air tank to continue to discharge into the measuring vessel and this air will be discharged out through the port 2G and out through the hose 3T with a hissing sound which would7 of course. draw attention to the fact that the valvey had not been closed and act, therefore, asta signal under these. circumstances. The utmost that could happen, under these circumstances, would be the exhaustion of the compressed air within the, tank 12 and the necessity of recom,-

pressing the air within thisv tank. If, when the valve 28 is moved to a filling position. that is a position in which the measuring vessel to be filled and after the vessel is filled. thc valve 2S isnot turned toits neutral position. thc onliy result' would be that the oil would continue to rise lthrough the within the measuring vessel and pass off pipe 25 and pipe 41 and out through the vent 43 back into the oil tank and eventually bubbles of air would rise up through the oil in the measuring vessel which would constitute a. signal or warning to the attendant that the valve had not been returned to its neutral position, and that under no circumstances, therefore. is there any waste of the oil which is returned under the last named circumstances to the tank itself without any loss and without the oil coming in contact with dust or dirt.

It is particularly desirable in a lubricat ing oil vending device of this chariuzter that the quality of the oil shall be capable of being seen and noted clearly hy the observer.

If the. observer has to look through a transparent cylinder having approximately a diameter of four or tive inches7 the extent of oil through which the observer has to look prevents clear observation of the quality of the oil and prevents him from seeing whether it contains foreign particles. diegs and the like. In order to prevent this` l provide means whereby only a small sample. as it were,`of the oil need he observed and to this end, I mount within the transparent wallv21 of the measuring vessel a metallic cylinder designated 44 which ma)y he made of any suitable material and which may be either polished or nickelplatcd or may be dull, as regards its` surface. This cylinder rests upon the base 2l) and at its lower end is preferably so formed that oil will flow from the interior of the measuring vessel to the exterior of this cylinder it. To this end I have formed the lower cnd of the cylinder 44 with struck-out portionsV `lil which are struck out and turned at right angles so as to hear against the wall 21 and hold the measuring c vlinde'r against the wall 21. This space is ordinarily approxinnitcly a half-inch from the-cylinder, though it may be more or less, these outwardly struck lugs 45 constituting centering lugs holding the cylinder in its proper position within the wall 21. By this means, only a rclativel7 small layer of oil is seen by the observer and he can practically look through this oil and see whether it containsl an v foreign particles, dirt, dregs and the like and thus he certain that the oil is not reclaimed oil.

It will be scenihatd have provided a structure which whilc vcr v simpl and which may be cheaplyv made. at the same time is proof against accidents of :in v description inasmuch as there is no possibility of pressure :u'cun'inlating within the measuring vessel or allied parts to an extent which would tend to burst this measuring vcsscl. It will lic further noted that l have provided a construction in which thi` oil cannot in contact with foreign matter. served CJI in all its purity and in which the .,e

lil

buyer can see, not only the amount of oil which he is getting, but see the quality of the oil through the transparentsides of the Vessehthus precluding any possibility of reclaimed or .so-called recleaned oil being substituted i'or the lubricating oil which he is buying.

The construction is such that the compressed air causes all of the oil to be forced out from the measuring vessel through the discharge hose into the car. Thus there is no chance of any oil being retained, but the purchaser knows he is getting a full amount of oil, for which he has paid, discharged into his car. Furthermore, it will be seen that my construction prevents any possibility of bursting of the measuring vessel through undue pressure and no oil is wasted. Again I have provided a construction Which is capable. ot being easily transported from one p0- sition to another and thus the oil is brought to the car'not in open cans from which it is liable to be slopped and in which the oil may be deteriorated by dust and dirt, but in a closed tank from which oil is discharged directly into the car without the intervention of any measuring vessel save that which forms a unitary part of the structure. lAt any time. that the air within the compressed air tank has become reduced below the necessary pressure, the compressed air tank may be readily filled with compressed air.

I claim In a liquid dispensing device having a liquid tank. an air pressure tank, pipe means connecting said pressure tank with said liquid tank, discharging means for discharging thev liquid from the liquid tank, and a compound valve interposed in the connecting pipe connecting said pressure tank to said liquid tank and also interposed in the discharging means` .said valve comprising a easing. a rotatable valve stem mounted in the casing. said casing having an inlet port, an outlet port and an Aoverflow port. said valve stein having an angularly disposed port therethrough whereby to permit intercommunication between selected ports. said valve casing also having a plurality of pairs ol`` oppositely disposed airports communirating with saidl pipe Connection and said pressure tank, said valve stem having a peripheral and an angularly disposed port therein permitting communication with sciected pairs ot air ports upon rotation of the valve stem` said air ports in said casing and said; .alve stem being disposed inA spaced relation to the liquid ports ot' said casing, said valvel stem upon rotation thereof for disv charge o t' liquid through the oischarge means being" adapted to connect selected air ports together whereby to permit forced discharge oll the liquid through the discharge port.
